DETAILED DESCRIPTION

The present disclosure describes various embodiments, systems, apparatuses, and methods that relate to junction box (jbox) interface chassis and pluggable modular devices. For example, the present disclosure describes variations of jbox interface chassis for installation in an electrical junction box, also known as a junction box, jbox, or J-box. The various embodiments of the jbox interface chassis include features for securing the jbox interface chassis to the junction box. The various embodiments of the jbox interface chassis also include an electrical interface for connecting wires in the junction box to electrical conductors on the jbox interface chassis and a corresponding rear pluggable interface electrically connecting pluggable modular devices. The various embodiments of the jbox interface chassis may also include locking features to selectively secure an installed pluggable modular device. In various embodiments, the locking features may be selectively actuated to release an installed pluggable modular device.

Various embodiments of pluggable modular devices include an electrical device with a pluggable device back for interchangeable and selective installation within a jbox interface chassis. A pluggable device adapter may be connected to legacy electrical devices to convert such legacy devices to pluggable modular devices for selective installation within a jbox interface chassis. In some examples, pluggable device adapters include electrical interfaces, such as conductor tabs, to electrically interface with legacy electrical devices.

Examples of pluggable modular devices (or legacy devices to which pluggable device adapters can be affixed) include, but are not limited to, a smoke detector, a carbon monoxide detector, a sensor, a doorbell chime, an AC to DC converter, an AC to AC converter, an LED light, a magnetic charging interface, a wireless charging interface, a wireless access point, a WiFi repeater, a cell phone signal repeater, a Bluetooth transmitter, a wireless network interface, a power monitor, a speaker, a fan, a switch, an outlet, a camera, a microphone, a voice assistant interface, a sleep monitor, a medical condition monitor, a temperature sensor, a projector, a holographic projection device, a wireless video transmitter, an infrared receiver, an infrared transmitter, a touch screen, a video screen, a battery charger, a removable portable speaker charger, a removable light charger, sensors or transmitters for enhancing augmented reality or virtual reality, a deodorizer, an air freshener, a mechanical hook, a thermostat interface, a communication port, audio-video ports, motion sensors, timers, smart home interface devices, and/or various combinations of any of the foregoing.

For example, a jbox interface chassis may include one or more fastener interfaces to facilitate the attachment and securing of the jbox interface chassis within an electrical junction box. For example, the jbox interface chassis may include holes or apertures to receive screws that can be screwed into threaded receptacles of an electrical junction box. The jbox interface chassis may further include a rear wire interface to which wires within the jbox interface chassis may be attached. For example, the rear wire interface may include screw terminals, wire-lock holes to receive and retain each wire within the electrical junction box, wires for attachment via wire nuts, solderable connections, and/or the like.

The jbox interface chassis provides an electrical connection between each of the wires in the electrical junction box and a front pluggable interface configured to receive a corresponding rear pluggable interface of various pluggable modular devices, as described in greater detail below. The jbox interface chassis may further include one or more retainer tabs configured to selectively retain an inserted pluggable modular device. In various embodiments, the retainer tabs may be manually actuated without the use of tools to selectively release a retained pluggable modular device so that it can be removed from the jbox interface chassis.

The pluggable interface, including the front pluggable interface of the jbox interface chassis and the rear pluggable interface on each pluggable modular device, may include corresponding slots and blades, corresponding pins and holes, a multi-pin cable interface, pressure contacts, wireless contacts, or the like. In various embodiments, the female slots or holes are included on the front pluggable interface of the jbox interface chassis such that a user can safely contact the exposed surfaces of an installed jbox interface chassis without fear of electrical shock. In another embodiment, the front pluggable interface may include a wireless power transfer interface, a wireless communication interface, and/or a wireless control interface for receiving instructions for the interconnection of the wires in the electrical junction box. In embodiments in which the jbox interface chassis includes a wireless power, communication, or control interface (a “wireless” front pluggable interface), each of the pluggable modular devices may include a corresponding rear pluggable interface, which may be referred to as a wireless rear pluggable interface.

According to such embodiments, pluggable modular devices may be hot-swappable into and out of an installed jbox interface chassis (e.g., the pluggable modular devices may be removed and installed without turning off the power to the wires in the electrical junction box). The pluggable modular device receives power, transmits communication signals, receives communication signals, and/or controls connections between the various wires in the electrical junction box via any of the various pluggable interfaces described herein, including the front pluggable interface of the jbox interface chassis and the corresponding rear pluggable interface on each pluggable modular device. As an example, a system that includes wireless pluggable interfaces may utilize inductive coupling, RFID, NFC, Bluetooth, capacitive coupling, and/or other wireless power transfer, wireless communication, and wireless control technologies.

For a single-pole electrical device, the jbox interface chassis may connect hot, neutral, and ground wires from the electrical junction box to a front pluggable interface. In such an embodiment, the front pluggable interface may include only three discrete pluggable ports. For three-way and four-way devices, such as three-way and four-way light switches, the jbox interface chassis may connect hot, neutral, ground, and one or more traveler wires to a front pluggable interface. In such an embodiment, the jbox interface chassis may include four or five discrete pluggable ports. In other embodiments, a standardized jbox interface chassis may be used that has three, four, five, six, seven, or even more discrete pluggable ports, regardless of the number of wires in the electrical junction box.

In some embodiments, the jbox interface chassis may connect AC electrical power from wires in the electrical junction box to the front pluggable interface. In some embodiments, the jbox interface chassis may additionally or alternatively connect DC electrical power and/or communication wires from the electrical junction box to the front pluggable interface.

Any of a wide variety of pluggable modular devices may be “plugged” into the front pluggable interface of the jbox interface chassis. Each pluggable modular device may include some type of external-facing electrical device. The external-facing electrical device may be, for example, a single-gang electrical device sized to fit within a jbox interface chassis installed in a single-gang of an electrical junction box. The electrical device is described as external-facing in that it interacts with or is accessible from outside of the electrical junction box. Numerous examples of external-facing electrical devices that can be embodied as pluggable modular devices are listed herein.

Each pluggable modular device may include a casing with a rear pluggable interface to provide electrical connections (including for AC power, DC power, electrical communications, optical communications, etc.) to the external-facing single-gang electrical device. In some embodiments, a device adapter may be used to convert existing or legacy electrical devices, such as single-gang light switches and single-gang outlet receptacles, into pluggable modular devices.

For example, a snap-on or screw-on casing or device back may be attached to a legacy electrical device. The casing may include conductor tabs, such as flexible or pronged conductor tabs, to electrically connect terminals of the legacy electrical device to a rear pluggable interface on the casing of the device adapter. Once the device adapter is mounted to the legacy electrical device, the combined device adapter and legacy electrical device function as a pluggable modular device that can be hot-swapped into and out of a jbox interface chassis.

In some embodiments, the casing may include pronged conductor tabs that are engaged by the screw terminals on a legacy electrical device as the casing is attached to the back of the legacy electrical device. In some embodiments, the casing may include access holes that allow a screwdriver or other tool to tighten the conductor screws on the legacy device against pronged conductor tabs in the casing of the adapter device. The casing may include any number of pronged conductor tabs strategically positioned to correspond to the conductor screws of any number of different legacy electrical devices. Some universal adapter devices may include flexible conductor tabs, rotatable or repositionable pronged conductor tabs, and/or other conductor tabs to interface with more than one type or brand of legacy electrical devices. Examples of legacy electrical devices include, but are not limited to, light switch devices and/or outlet receptacles.

A pluggable modular system may include a jbox interface chassis to be fastened within an electrical junction box and connected to the wires within the electrical junction box. The pluggable modular system may also include any number of hot-swappable modular devices that can be interchangeably plugged into the jbox interface chassis and removed from the jbox interface chassis. Once the jbox interface chassis is wired and secured within the electrical junction box, an average consumer can interchangeably swap pluggable modular devices into and out of the jbox interface chassis to change the functionality and/or upgrade the functionality as desired.

Many existing manufacturing techniques may be utilized to produce the various embodiments of jbox interface chassis, pluggable device adapters, and pluggable modular devices. Examples of suitable manufacturing techniques include, but are not limited to, three-dimensional printing and other additive manufacturing techniques, milling, machining, polymer casting, rotational molding, vacuum forming, injection molding, extrusion, blow molding, and other manufacturing techniques.

The various jbox interface chassis, pluggable device adapters, and pluggable modular devices may be designed, adapted, modified, and/or manufactured to conform to specific standards for interoperability with existing and legacy devices and components. For example, the jbox interface chassis described herein may have dimensions specifically selected to fit within existing or legacy electrical junction boxes, such as those conforming to the specifications set by the National Electrical Manufacturers Association (NEMA), the American National Standards Institute (ANSI), and/or the National Electric Code (NEC). For example, jbox interface chassis may be manufactured with dimensions conforming to the NEMA OS1 and/or NEMA OS2 standards or similar standards in foreign jurisdictions and countries. In various embodiments, the jbox interface chassis, pluggable device adapters, and/or pluggable modular devices may be manufactured in conformance with NEMA, ANSI, and/or NEC specifications and certified by organizations such as the Underwriters Laboratories (UL), Edison Testing Laboratories (ETL), Conformance European (CE), other Nationally Recognized Testing Laboratories (NRTL), or the like.

A wide variety of computing devices and infrastructures may be used in combination with the presently described systems and methods. Some of the infrastructure that can be used with embodiments disclosed herein is already available, such as general-purpose computers, computer programming tools and techniques, digital storage media, and communication links. A computing device or controller may include a processor, such as a microprocessor, a microcontroller, logic circuitry, or the like.

A processor may include a special-purpose processing device, such as an application-specific integrated circuit (ASIC), programmable array logic (PAL), programmable logic array (PLA), a programmable logic device (PLD), a field programmable gate array (FPGA), or another customizable and/or programmable device. Various aspects of certain embodiments may be implemented using hardware, software, firmware, or a combination thereof.

According to the illustrated installation, the pluggable modular paddle switch devices 1190 and 1191 may be hot-swappable and selectively removed from the jbox interface chassis 1100 and 1101 by releasing the retainer tabs 1126.

In an alternative installation, the screws 1131 may be removed and passed through the aperture in the pluggable modular paddle switch devices 1190 and 1191 and the aperture in the jbox interface chassis 1100 and 1101 before being threaded into the double-gang electrical junction box 1130. With such an installation, the pluggable modular paddle switch devices 1190 and 1191 are more securely retained. In some embodiments, special screws or other locking fastener devices may be utilized to prevent theft or malicious removal of the pluggable modular paddle switch devices 1190 and 1191 from the jbox interface chassis 1100 and 1101 and underlying double-gang electrical junction box 1130.
